TROUBLESHOOTING CHARTS
FLASH CODE:
75
DDR DISPLAY:
ECM BATTERY VOLTAGE HIGH
SAE J1587 CODE:
PID: 168 FM: 0
Indicates that the DDEC III ECM has detected that the main battery supply voltage to the ECM has exceeded the
recommended operating range.
FLASH CODE:
76
DDR DISPLAY:
ENGINE OVERSPEED WITH ENGINE BRAKE
SAE J1587 CODE:
PID: 121 FMI: 0
Indicates that the engine RPM (while the engine brake is ON) has exceeded the recommended safe operating range.
FLASH CODE:
81
DDR DISPLAY:
OIL LEVEL SENSOR INPUT VOLTAGE HIGH
SAE J1587 CODE:
PID: 098 FMI: 3
Indicates that the Oil Level Sensor (OLS) input to the ECM has exceeded 95% (normally > 4.75 volts) of the sensor
supply voltage. This diagnostic condition is typically:
(1)
open sensor return circuit
(2)
sensor signal circuit is shorted to the sensor +5 volt supply
FLASH CODE:
81
DDR DISPLAY:
CRNKCSE PRESS SENSOR INPUT VOLTAGE HIGH
SAE J1587 CODE:
PID: 101 FMI: 3
Indicates that the Crankcase Pressure Sensor input to the ECM has exceeded 95% (normally > 4.75 volts) of the
sensor supply voltage. This diagnostic condition is typically:
(1)
open sensor return circuit
(2)
sensor signal circuit is shorted to the sensor +5 volt supply
FLASH CODE:
81
DDR DISPLAY:
DUAL FUEL BOI INPUT VOLTAGE HIGH
SAE J1587 CODE:
SID: 020 FMI: 3
Indicates that the Dual Fuel (Diesel/Natural Gas) ECM BOI output control signal to the DDEC III ECM has exceeded
the calibratible maximum level.
FLASH CODE:
82
DDR DISPLAY:
OIL LEVEL SENSOR INPUT VOLTAGE LOW
SAE J1587 CODE:
PID: 98 FMI: 4
Indicates that the Oil Level Sensor (OLS) input to the ECM has dropped below 5% (normally < 0.25 volts) of the
sensor supply voltage. This diagnostic condition is typically:
(1)
open sensor signal circuit
(2)
open sensor +5 volt supply circuit
(3)
sensor signal is shorted to the sensor return circuit or to ground
(4)
sensor +5 volt supply is shorted to sensor return circuit
